We agree that as well as tracking how many children are in poverty as currently measured, it is helpful to track what is happening to the factors that lead to poverty and the barriers to children's life chances. But it does not make sense to combine all of these into a single measure. To do so would open up the government to the accusation that it aims to dilute the importance of income in monitoring the extent of "poverty" at precisely the time that its policies will be reducing the real incomes of poor families. We call on the government to reconsider its proposals.

The importance of unpaid care was reflected by its inclusion as an item in both censuses in 2001 and 2011 and made it possible to compare over time the dramatic rise in the number of unpaid carers over a national, regional and local level. In England there was a clear north-south divide with the highest percentages of care provision being in the North West, North East, East Midlands and West Midlands. Across local authorities the number of carers increased in 320 authorities and fell only in six. In Birmingham, the number of unpaid carers increased by more than 9,000. The highest increase in the extent of unpaid care occurred in the 50 hours or more per week category, which clearly places an additional burden on the work-life balance of those relatives, friends and other informal carers providing it.

If organisational culture were a person he'd be feeling utterly hacked off by now. Rarely consulted about anything that happens in the organisation, he always takes the heat when things go wrong.Culture, it seems, is to blame for the problems at Mid-Staffordshire NHS trust, the wider NHS, Barclays, RBS and the Civil Service. That's just from one week's headlines.It's a useful catch all for that stuff that no-one can really explain but that just seems to somehow go on in the organisation. It is rare that anyone attempts to define what culture is. Perhaps that's the point. The cloudier it is, the more stuff you can hide inside it.Calls for culture change are easy to make but harder to do.

• A new photography exhibition opening this week in west London, exploring the role of faith in the community. Faith in Suburbia: a shared photographic journey, at Gunnersbury Park Museum in Ealing, records a collaboration between older members from six different faith communities in the area. Through photography, they explored each other's worship spaces. One participant said:

When you're using a camera you see the details, the patterns, the similarities between different places.

While another commented:

Visiting the mosque and the Sikh temple and other places of worship has opened my eyes ... it has broadened my mind in many ways. If other people did this it could bring the world together in a small way or even a big way.

I am now experiencing the world in a more childlike way. It is like my senses are reawakening after being numbed and lost in freezing fog for three years.Depression had drained the colour from my life, deadening my memory, blackening my moods and draining my energy and enthusiasm. I go out now and look up at the trees and sky, rather than staring blankly ahead or at the floor. Like my children, I'm enjoying exploring the world around me and taking in new experiences.
